Is your diaries information correct?
2500-PPM and EC-5 is cray high. I'm am surprised they are alive if that is correct reading.
You may need to calibrate your TDS pen and confirm the numbers are true.
If they are real, you need to lower the feed immediately and flush it out.
If the numbers are not correct you maybe underfeeding your plants. you can use 1/2 of the feeding schedule recommended by AN but keep calmg normal. Auto's are not as heavy feeders and like less.
your lighting also says its 17/7, 18/6 or 24/0 is the ideal settings. I prefer 18/6 myself for autos.
Best Of Luck and Happy Growing!

Meant to say 20/4 not 24/0**

my 2 cents:
the yelowing looks N deficiency, but yes, it looks she's recuperating. the spots look like K deficincy to me. overall this plant looks underfeed.

Looking at one healthy one, I would bet that's it's aftermath of ex hickups .
Good pH for Coco, go with higher bit, close to 6.0, you had Cal mag issues and they need if against strong LEDs.
If new grows healthy, you ok, but feed and pH will be crucial points for harvest size.
All the best !

She still seems pale-ish to me. Been feeding what I think is enough nutrients, I may be wrong. New growth always seems kinda nitrogen abundant cuz they very green but seem to keep fading as newer higher leafs grow. Should I flush or add more nutrient? Starting week3 flower

Too much light or PH imbalance?I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent?
Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?

Grower questionAny ideas what the issue could be?
Few weeks into flower. Dealing with fungus gnats and have kept the population very low.
Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED).
I have adequate air flow.
